addresses are not toggling. The device can be put into standby

mode reducing power consumption by more than 99% when

deselected Chip Enable 1 (CE₁) HIGH or Chip Enable 2 (CE₂)

LOW. The input/output pins (I/O₀through I/O₇) are placed in

a high-impedance state when: deselected Chip Enable 1

(CE₁) HIGH or Chip Enable 2 (CE₂) LOW, outputs are disabled

(OE HIGH), or during a write operation (Chip Enable 1 (CE₁)

LOW and Chip Enable 2 (CE₂) HIGH and WE LOW).

Writing to the device is accomplished by taking Chip Enable 1

(CE₁) LOW and Chip Enable 2 (CE₂) HIGH and Write Enable

(WE) input LOW. Data on the eight I/O pins (I/O₀through I/O₇)

is then written into the location specified on the address

pins(A₀through A₂₀).

Reading from the device is accomplished by taking Chip

Enable 1 (CE₁) and Output Enable (OE) LOW and Chip

Enable 2 (CE₂) HIGH while forcing Write Enable (WE) HIGH.

Under these conditions, the contents of the memory location

specified by the address pins will appear on the I/O pins.

The eight input/output pins (I/O₀through I/O₇) are placed in a

high-impedance state when the device is deselected (CE₁

LOW and CE₂HIGH), the outputs are disabled (OE HIGH), or

during a write operation (CE₁LOW and CE₂HIGH and WE

LOW). See the truth table for a complete description of read

and write modes.

Features

• Very high speed: 55 ns and 70 ns

— Wide voltage range: 2.20V – 3.60V

• Ultra-low active power

— Typical active current: 2 mA @ f = 1 MHz

— Typical active current: 15 mA @ f = f_max

• Ultra-low standby power

• Easy memory expansion with CE₁, CE₂and OE features

• Automatic power-down when deselected

• CMOS for optimum speed/power

• Packages offered in a 48-ball FBGA

Functional Description^[1]

The CY62168DV30 is a high-performance CMOS static RAMs

organized as 2048Kbit words by 8 bits. This device features

advanced circuit design to provide ultra-low active current.

This is ideal for providing More Battery Life (MoBL^) in

portable applications such as cellular telephones. The device

also has an automatic power-down feature that significantly

reduces power consumption. The device can be put into

standby mode reducing power consumption by 90% when
